Synthesis of GSK3β mimetic inhibitors of Akt featuring a novel extended dipeptide surrogate
摘要:
Akt is a cardinal nodal point in PI3K signaling pathway and confers resistance to apoptosis through inactivation of regulatory substrates such as GSK3 beta. Efforts to inhibit the kinase activity of Akt have largely focused on targeting the ATP-binding domain of Akt. Here, we present the design and synthesis of conformationally constrained GSK3 beta mimics featuring a novel extended dipeptide surrogate core. This effort resulted in the identification of a novel substrate mimetic Akt inhibitor (11) with low micromolar activity in vitro (Akt1 IC50 = 3.1 mu M). (C) 2011 Elsevier Ltd. All rights reserved.
